Adding mutiple matrices

Hi, I am trying to add many(about 192) matrices into one. Maybe there is a better way to do this? I have a number of still images that I want to replace cells of a video. Each image location corresponds to the location and of a specific cell and value. Is there a less processor intensive way to combine these images other than "jit.op @op +" or "jit.glue"? This is A rough vesion of what Ive got. Any suggestions or help would be appreciated. Thank you…
